(54) Electricity generation system


(57) An electricity generation system according to the present invention comprises a first electric generator (21) designed to generate electricity by rotation of a highpressure shaft (122) of a compressor (12) constituting a jet engine, a second electric generator (22) designed to generate electricity by rotation of a low-pressure shaft (121) of the compressor (12), a power distributor (28) for distributing power generated by the first and second electric generators (21, 22) among multiple loads, a first power regulation device (25) for regulating power output of the first electric generator (21), a second power regulation device (26) for regulating power output of the second electric generator (22), and a power control device (29) which manipulates the first and second power regulation devices (25, 26) to ensure a specified amount or greater of jet engine surge margin.
